112P
Self-POwered
COAXIAL
Loudspeaker
The 112P combines the significant
advantages of L-ACOUSTICS® coaxial
point source technology with
the convenience of self-powered
performance and the power of digital
signal processing.
Self-powered, two-way
enclosure (12" LF, 1.4" HF)
Ideal for multi-purpose, portable sound
reinforcement, the 112P features
advanced loudspeaker components powered by a 1000 W
amplifier module with dedicated
on-board digital signal processing. Four
application-engineered presets are
available (FILL, FRONT, MONITOR,
X-OVER), complementing the considerable flexibility of the 112P by providing
convenient, plug-and-play ease of
operation.
High power coaxial
driver assembly
Coherent point source
radiation (90° axi symmetric directivity)
High efficiency power
amplifier module
Digital system equalization
(FILL, FRONT, MONITOR,
Featuring a 1.4" exit compression driver
coaxially-loaded by a 12" transducer,
the 112P provides coherent point
source radiation with 90-degree
axi-symmetric directivity (identical
horizontal, vertical and axial coverage).
Due to the coaxial component configuration, power response is free of the
polar lobing effects typical of traditional
horn / woofer combinations.
The net result is natural, studio monitor
sound quality - ideal for proximity
fill use or portable distributed sound
reinforcement in theatre, congress
centre, concert hall, trade show,
corporate A/V, house of worship,
club, or television applications. When
used with the L-ACOUSTICS SB15P
self-powered subwoofer, the 112P
is also highly suitable for side fill,
drum monitoring or medium format
front-of-house (FOH) applications.
Due to its compact, wedge-shaped
enclosure format, the 112P provides
an exceptionally high performance
floor monitor solution. Excellent image
and coverage stability is obtained due
to the coaxial configuration and the
performer experiences a generous,
homogeneous coverage pattern
without the subjective impression
and potential feedback problems of
listening to a separate horn / woofer
combination.
To facilitate installation, pole mount
sockets are included as standard and
optional rigging accessories include an
adjustable U-bracket (for ceiling, wall,
scaffold or truss mounting).

L-acoustics specifications are based on measurement procedures which produce unbiased results and allow for realistic performance prediction and simulation.
Some of these specifications may appear conservative when compared with other manufacturer ’s specifications. All measurements are conducted under free field
conditions and scaled to a 1 m reference distance unless otherwise indicated.

Additional Equipment
•L-ACOUSTICS SB15P subwoofer
The enclosure shall be a self-powered, two-way, coaxial full range loudspeaker
containing one direct radiating, bass reflex-loaded, weather-resistant 12-inch
low frequency transducer and one 1.4-inch exit, 3-inch voice coil diameter,
titanium alloy diaphragm compression driver. The cone body of the low frequency
component shall provide pattern control loading for the compression
driver and yield a 90-degree conical directivity pattern that is axi-symmetrical.
As a full range system, the frequency response shall be 60 Hz to 18 kHz
with less than ± 3 dB variation and the usable bandwidth shall be 50 Hz to
20 kHz (-10 dB).
